The BDA could stop the HDR confusion in consumers' minds.

But consumers don’t have to endure hardship of audio format war thanks to the consumer-driven audio/video receivers (AVR) makers. They support all audio formats. It is not their logic business to interfere in consumer choice: a playback device should be able to play any existing content the consumers want.
Different audio or video formats are just different software running on playback devices (AVR, media player, TV).
Furthermore, software development is much easier and faster on modern operating systems of HDR TV than on rigid and complex DSP platforms of audio/video receiver.
We, consumers, can’t let "what happens in the industry happens".
After all, we, consumers, pay!
Consumers can just require Dolby Vision TV makers or HDR10+ TV makers to just add a piece of HDR software in order to be compatible with the other HDR format. This upgraded TV will remain the same: same panel, same electronic parts, same mechanical parts!
For example, the Sony Z9D doesn’t support Dolby Vision at launch.
Sony already made the announcement - no Dolby Vision support.
Someone mentioned that Samsung's dynamic metadata HDR10 proposal passed with the competent authorities and perhaps we will see something like a dynamic HDR update on the Z in the future, but this is pure speculation.
Nobody should buy this set expecting a DV upgrade in the future - it simply ain't happening.
Later, the Sony Z9D will get Dolby Vision with a free software upgrade.
Dolby Vision is currently the most complex HDR format due to its dynamic metadata color volume mapping and its 12-bit dual layer architecture. Therefore, if a TV’s SoC like the Sony Z9D TV's SoC is powerful enough to support Dolby Vision, this SoC is able to support any other HEVC HDR format like HDR10+.
In the same way, if a UHD Blu-ray player’s SoC is powerful enough to support Dolby Vision, this SoC is able to support HDR10+.
The BDA wants to avoid a HDR format war, because a format war is detrimental to consumers, and therefore to its members (manufacturers, movie studios …).
In exchange for the addition of HDR10+, the BDA should require the TV makers to support both HDR10+ and Dolby Vision.
